ELECTRIC srovn.

Application filed ember 1e, 1:524. Serial no. teams.

The principal objects of the invention are to devise an electric range particularly adapted for heavy duty such" as required for hotel and restaurant service presenting the maximum area of a uniformly heated stove PA further important object is to provide a stove top which will retain a uniformly level surface and a still further object is to W provide a structure from which the heating elements may be easily and quickly removed and replaced.

The principal features of the invention consist in the novel construction of the stove top whereby the heat from heating elements arranged thereunder is uniformly distributed and the top is restrained from distortion by a plurality of ribs arranged on the underside thereof and in the novel arrangement ml of the heating elements in units capable of being readily withdrawn.

A still further feature consists in the novel arrangement of slidable trays beneath the heating elements of the top. 4

Tn the drawings, Figure 1 is a perspective view of the improved stove showing the oven door open and some of the heating elements partly; removed, the switch panel being also swung open,

Figure ais an enlarged sectional detail illustrating the manner of connecting the elements with the electrical conductors.

Figure 3 is a cross sectional view of a be used. It is the purposeof this invention to provide an assembly for a stove which will be capable of quick adjustment and ready replacement of elements and to provide an'extraordinary heating equipment for the stove top which will present the maximum heating area and will provide a uniform heat for utensils placed on any portion of the to lin. the construction herein shown, the stove frame 1 is of a sturdy type and is constructed with a raised top portion 2 spaced from the oven section. Cast iron plates 3. are supported in the raised portion 2 of the frame and these are constructed with ribs 3' on the underside preferably arranged parallelly and extending longitudinally from end to end thereof. The tops of these plates provide a uniform [level heating surface upon which utensils may be placed at any spot and the ribs 3' distribute the heat uniformly and prevent warping.

Beneath the plates 3 are arranged a plurahty of sheet metal receptacles 4 in which are arranged suitable electric heating elements. These receptacles are open at the to and the heat of the elements is radiated directly against the under surface of the" ribbed top plates. The heat is thus distributed over the entire surface of the plates very uniformly.

The receptacles are each provided with pro ectlng contacts 5 as illustrated in sectional detail in Figure 2. These contacts extend into insulating blocks 6 arranged at the back of the stove structure and engage the electric terminals -7 arranged back of the blocks 6.

By this construction it will be seen that any one of the receptacles a may be withdrawn from under the plate 3 and replaced coincidently with a new receptacle.-

Below the receptacles 4 are arranged the slide trays 8 which serve to support the receptacles 4 when they are drawn out, or they may be used when the stove is in service as supports for pans or utensils where the cook is preparing food before placing upon the hot top or when in position-beneath the elements they will serve to catch any fra ments or fluids which might fall throng the elements;

In the oven structure the lower heatin elements are contained in receptacles 'Slmk lar to those arranged under the top and suitable contact blocks are arranged at the hack of the stove to engage the contact fingers.

The upper stove oven elements are slidably supported in suitable guide-ways dependent from the top of the stove oven. All

the elements are provided with projecting contacts adapted to engage the contact fingers arranged in the insulated back of the stove.

The electric wiring to the various elements is carried to a panel casing 9 vertically arranged at one 'end of the stove and within this casing is arranged the fuse blocks 10. The switches are supported upon a hinged panel 11 forming the cover to the vertical casing 9.

A stove constructed as described is extremely serviceable as the arrangement of heating elements for both the top and oven is such as to give the maximum amount of heat and covering practically the entire surface of the top and bottom of the oven and the underside of the stove top.

What I claim as my invention is 1. An electric stove comprising an oven structure having a closed top spaced thereabove and forming a compartment separate from the oven and open at the front, horizontal guide-Ways arranged beneath said top and extending from front to back of said compartment, a plurality of receptacles slidably arranged in said guide-ways and closing said 0 en front, separate individual electric heating elements arranged in said receptacles, electric contacts secured to said heating elements and extending rear- Wardly from said receptacles, and :electrical socket contacts arranged in the, stove frame to the rear of said compartments.

2. An electric stove, comprising, a frame having a hollow back, a plurality of insulating blocks having perforations there through and secured in said hollow back, electrical contacts arranged on said insulating blocks, and a group of individual independent electric heating units slidably supported at various levels in the stove frame and having contact fingers adapted to extendthrough said blocks to engage the contacts thereof, the units composing each of said groups being all arranged in a common horizontal plane, and switches controlling the current to said individual heating units.

3. An electric stove, comprising, a frame, a plurality of electrical contacts arrangeo in said frame, removable electric elements connected with said contacts, a vertical casing arranged at one side of the stove, fuse blocks arranged one above the other Within said casing, a cover for said casing hinged thereto at the bottom and adapted to swing outwardly and downwardly, and switches for controlling the circuit carried by said cover.
